Converter 350/400 2200-2600 Stall

The Converter 350/400 2200-2600 Stall torque converter is engineered for serious street and strip performance on TH350 and TH400 transmissions. Designed by Allstar Performance, this converter bridges the gap between stock efficiency and full-race capability, making it the choice for builders seeking improved launch characteristics without sacrificing drivability. Whether you're upgrading a classic muscle car, modern restomod, or performance street machine, this stall converter delivers the responsiveness and engagement modern drivers demand.

At 2200–2600 RPM stall, this converter holds the engine at optimal RPM during launch before locking up, allowing maximum torque multiplication when you need it most. The 10.750-inch bolt circle ensures direct fitment to both TH350 and TH400 transmission housings with zero modification. Internal fluid dynamics are precisely tuned to balance quick off-the-line acceleration with highway cruising comfort; the converter locks up at highway speeds to restore fuel efficiency and reduce heat. Weighing 28.57 lbs, it maintains durability through quality internals while keeping rotational mass reasonable for overall engine bay balance.

This converter is ideal for street performance, bracket racing, and weekend warriors who want immediate throttle response and reliable power delivery. Compatibility spans decades of vehicles running TH350 or TH400 platforms—from 1960s Chevelles to modern LS-powered builds. Professional installers and experienced DIY builders appreciate the bolt-and-go installation; no core exchange required, and the compact 14.25 x 7.5 x 14.25-inch envelope fits standard mounting locations. For anyone serious about transmission performance without the complexity of a full rebuild, the Converter 350/400 2200-2600 Stall represents proven engineering at a practical price point.
